If he’s held stable for a prolonged period, that is hopeful. When my ‘rona pneumonia didn’t improve for the first two weeks, but didn’t worsen, the doctors took that as favorable.
Did you get placed on a ventilator? I know folks recover even after the ventilator, but that seems to be the kiss of death. I don’t know the survival rates once placed on one.
He is on the lung portion of a heart/lung machine I believe. They have said several times his lungs are not good.
